  • . The surface morphology of the original substances and the PBS/CNTs nanocomposites was studied using SEM (Figure 1). In Figure 1a, the typical surface structure of PBS is visible. CNTs appear as agglomerates ranging from 500 nm to 200 μm, composed of woven nanotubes with an outer diameter of 14 to 28
  • nm and a length of up to 40 μm (Figure 1b). The microstructure of PBS/CNT_10 (Figure 1c) and PBS/CNT_0.5 (Figure 1d) samples is quite similar. In the SEM images of both samples, small white inclusions (nanotubes) ranging from 24 to 200 nm in size are evenly distributed over the surface. On the

  • , atomic force microscopy, and transmission electron microscopy analyses revealed that the TaN films exhibit excellent crystallinity and smooth surface morphology, when deposited at optimal temperatures of 750 and 850 °C. The films exhibit superconducting transition temperatures (Tc) ranging from 5.0 to
  • . Atomic force microscopy (AFM, XE-70 Park Systems) in contact mode was used to study the surface morphology of the films. The synthesis protocol used in this study was modified from the work reported by Quintanar-Zamora et al. [15] by varying the substrate temperature and the nitrogen pressure. Results
  • -vacuum conditions, a small residual oxygen concentration inevitably remains within the deposition chamber. At elevated temperatures, the reactivity of these residual oxygen molecules increases, facilitating their adsorption onto the growing film surface. However, an increase in N2 pressure can lead to

Graphical Abstract
  • force microscopy (KPFM) is an important tool for conducting such studies, enabling the measurement of the perovskite’s surface potential by monitoring the electrostatic force between the surface and a conductive probe (See Supporting Information File 1, Section 1). This measurement can provide insights

Therefore, the surface potential profile of a forward biased device can be correlated with the potential distribution under illumination and open circuit [43][44][45] (See Supporting Information File 1, Section 2). By forward
